I like spalted wood, I don't treat it any different than normal wood TBH. Although using hand tools I'm making a lot less dust anyway.
MB pallets were banned over here about 15 years ago, saying that my new kitchen floor just turned up on one. Normally I'd go nowhere near it, but it seems to be made of birch, with some red oak in the top crate, so I suspect I'llĀ end up using it.
Over here the MB pallets just have the normal stamp, with MB where you want to see HT (Heat Treated).
